In the cooking of doughnuts in a machine employing a longitudinally traveling conveyor in which the doughnuts are arranged abreast, considerable diiculty has been encountered in machines having a plurality of doughnut formers in that it is practically impossible to cause all of the doughnut formers to deliver doughnuts of the same size and shape. Where a traveling doughnut former has been utilized adapted to deliver at different localities with respect to the longitudinal conveyor, it has further been found extremely inconvenient due to the fact that only a small receptacle for dough could be utilized and great diculty was encountered in filling this receptacle during the operation of the machine. In addition distortion of the doughnuts occurred through movement of the receptacle. The present invention provides a machine by means of which all these disadvantages are eliminated.

My invention, which is best shown in Fig. 1, consists of a framework III which carries'anelongated receptacle I I for the reception of a cooking liquid which may be heated in any desired manner, and along which the doughnuts are progressed during the cooking thereof. At the forward end of the machine is provided a longitudinally extending conveyor I2 and at the rearward end of the machine is another longitudinal conveyor I3 by means of which the doughnuts are progressed along the receptacle II. Between these conveyors is disposed a turnover device I4 (Fig. 7) which causes the doughnuts to be inverted to procure uniform cooking on both sides thereof. At the forward end of the doughnut machine is provided a doughnut former I 5 which is adapted to discharge the doughnuts into the receptacle I I. A transverse conveyor I6, Fig. 2, deliversgthe doughnuts from the doughnut former I5 to positions from which the s ame may be picked up by the conveyor I2 and progressed through the receptacle I I. vice indicated in its entirety at I1 serves to intermittently operate the two conveyors I2 and I3 simultaneously and to alternately therewith operate the turnover device I4. Another transmission mechanism indicated in its entirety at I8 serves during the cessation of operation of the conveyors I2 and I3 to operate the doughnut former I5 and the conveyor I6 alternately and to operate the same a number of times equal to the number of columns of doughnuts progressed through the machine. These various parts will now be described in detail.

The frame III consists of two longitudinal frame members I9 and 20 which are supported on a number of posts`2I, 22 23, 24, and 25. The frame members I9 and 20 may be constructed as angles and are arranged with the flanges 26 and 21 extending downwardly and outwardly` as best shown in Fig. 3. The posts 2I are disposed inwardly of the flanges 26 and are riveted or welded thereto. The posts 23, 24 and 25 are secured to the outer surfaces of the flanges 26 and are similarly attached thereto. For transversespacing of the longitudinal frame members I9 and 20, three transverse frame members 28, 29 and 30 are employed of which the frame members 28 are attached to flanges I9 and 20 at the rear ends thereof and of which the frame members 29 and 30 are secured to the transverse flanges of the posts -2I and 22. These frame members are dropped considerably below'. the longitudinal frame members I9 and 28 and serve a'purpose to -be presently described in detail. In addition to these frame members two other transverse frame members 36 and 31 are employed which are attached to the posts 2I and 25 near the lower ends thereof.

The posts 2l, 2,2, 23, 24, and 25 are reinforced through tie rods 3| which may consist of angles secured to the inner surfaces of the longitudinally extending flanges of these posts and riveted thereto. Suitable braces 32 and 33 secured to the longitudinal frame members I9 and 20 and to posts 2I and 25 brace the entire frame structure longitudinally. Similar braces 34 and 35 secured to the posts 2| and 25 and to the transverse frame members 36 and 31 brace the frame structure transversely.

The receptacle I I is in the nature of a shallow pan or tank constructed with a bottom 38 and sides 39 and 48. This receptacle provides an elongated way along which the doughnuts are The transmission dewhole number of doughnuts. vmachine shown, the receptacle and conveyor are members dinal frame members if desired through bolts 42,

best shown in Fig. 2. The receptacle I I is formed at the rear with an end indicated in dotted lines at 43 in Fig. 1 which inclines from the bottom 38 up to the upper edges of the two sides 39 and 40. The front of the receptacle II is constructed with a depressed portion 44 best shown in Figs.- 2 and 9 in which the transverse conveyor I6 is disposed. This depressed portion is constructed with transverse walls 45 and 46 and end walls 41 and 48.

'The transverse wall 45 is offset at 49 to provide a chamber 50 within the receptacle in which transmission mechanism for driving the conveyor I6 may be disposed. The receptacle II is further formed with an end wall 5I at the extreme forward portion thereof.

Conveyor I2 is best shown in Figs. 1, 2, and '1. 'I'his conveyor consists of two endless chains 52 and 53 which pass over sprockets 54 and 55 secured to two transverse shafts 56 and 51. The shaft 51 is journaled in bearings 58 attached to the upper ends of the posts 22. These bearings are formed with slots 59 through which bolts 60 extend whereby the said bearings may be slid along the upper portion of the receptacle II to procure tightening of the chains I2. 'Ihe shaft 56 is journaled in a bearing formed in ythe transmission I1 and is further journaled in another bearing similar to the bearings 58 but not shown in the drawings. For the purpose of propelling the doughnuts through thecooking liquid, a number of blades 268 are employed which are attached to the chains 52 and 53 and which issue outwardly therefrom. 'I'hese blades are formed with flanges 6I which lie in the plane of the runs of said chain and which are secured to certain links of the chain in any'suitable manner. The distance between the blades 260 is somewhat greater than the diameter of the doughnuts so that the doughnuts may be freely received therebetween and progressed. The width. of the receptacle II and the corresponding width of the blade 260 is equal to or slightly greater than a In the particular of a width suflicient to propel four doughnuts abreast along the receptacle I I.

Conveyor I3 is constructed in identically the same manner as conveyor I2, being provided with chains 62 which pass over sprockets 63 and 64. vThe sprockets 63 are mounted on a shaft 65 journaled in the transmission device I1 and in another bearing similar to that used for shaft 56. The sprockets 64 are attached to a. shaft 66 which is journaled in bearing 61 attached to the outer ends of the longitudinally extending frame I0. 'I'hese bearings are adjustable along said frame members so that the slack in the chain may be taken up as wear occurs. At-

tached to the chains 62 are a number of blades two chains I2 and I3 the doughnuts 'may be 7 5 progressed from one end o1' the receptacle to the other.

The various chains 52, 53, and 62 ride upon4 -cured to these rails extend downwardly into the cooking liquid and prevent the doughnuts from passing under said rails.

The two shafts 56 and 05 of conveyors I2 and I3 are spaced from one another to provide room for the turnover device I4 which is disposed between the same. This turnover device consists of ,a square shaft |69 which is provided at its ends with trunnions 10 adapted to be journaled in bearings 1|. Bearings 1I are disposed upon the interior of the receptacle I I and are attached to the sides 39 and 40 through rivets 12. The shaft 69 has attached to it two blades 13 ,and 14 which are so disposed as to operate between the blades 68 and 260 of the .two conveyors I2 and I3 and to receive the doughnuts discharged by the blades 260, turn them over and deliver them to the blades 68 of conveyor I3. 'I'he bottom 38 of the receptacle II is depressed as designated at 15 to provide space for the operation of the blades 13 and 14 as the shaft 69 rotates.

At the bottom of the receptacle 38 is provided a number of electrical heating elements 16 by means of which the cooking liquid in the recepv tacle Il may be maintained at the proper temperature. These heating elements are diagrammatically illustrated and it can readily be comprehended that any suitable construction such as is now in common use for this purpose may be employed. Also extraneous heat, as from gas flame may be utilized to maintain the proper temperature or any other suitable heating means employed.

For the purpose of procuring discharge of the doughnuts from the receptacle II the upwardly inclined rear end 43 of said receptacle is utilized. At such locality the lower run 11 of conveyor I3 is caused to inclinev in parallel relation with respect to the end wall 43. This is accomplished by utilizing two idler sprockets 18 which are mounted on a Shaft 19 journaled in bearings 80 which are secured to the upper flange 21 of the two longitudinal frame members I9 and 20. The sprockets 18 bear against the lowermost run of the said conveyor. In conjunction therewith the bearings 61 are somewhat elevated to cause the blades 68 on said conveyor to follow closely to said end wall. As the doughnuts reach the said end wall the blades 68 cause the same to climi; the end wall and to be discharged from the rear end of the machine.

In the operation of the two conveyors I2 and I3 and the turnover device I4, the two conveyors are simultaneously operated. 'I'hese conveyors are operated intermittently with respect to the turnover device I4. When the conveyors I2 and |3 function the turnover device I4 is disposed with the blades 13 and 14 thereof arranged as shown in dotted lines in Fig. 7. When the two conveyors I2 and I3 come to rest the blades thereof become disposed as shown in full lines in Fig. 7. During such period the turnover device I4 operates to receive the doughnuts discharged by conveyor I2 and to turn the same over and to deliver the doughnuts to a position whereby the same may be engaged by the blades 68 of conveyor I3. For the lpurpose of procuring the alternate periodic movement of these parts I the transmission device I1 previously referred to is employed. This device is best shown in Figs. 6 and 8 and comprises a gear case 8|. The gear case 8| has a back 82, ends 83 and 84, atop 85 and a bottom 86being open at the front thereof. The bottom 86 rests directly upon the flange 21 of frame member I9 and is provided with feet 88 and 89 also resting upon said ange. Bolts 90 passing through said feet and the fiange 21 of frame member I9 serve to hold 'the case 8| rigidly attached to the said frame member. 'I'he open forward portion of the case 8| is adapted to be closed through a cover plate 9| which is bolted to a flange 92 formed on the ends 83 and 84 and the top 85 and bottom 86 of said case. This is accomplished through cap screws 93 which pass through said cover plate and are screwed into the flange 92.

As previously stated, the two shafts 65 and 56 which carry the sprockets 63 and 84 of conveyors I3 and I2 extend into the gear case 8|. These shafts are journaled inl bearings 94 and 95 formed is attached to the inner end of the shaft 56. An-

other sprocket |00 of the same size as sprocket 99 is likewise secured to the inner end of the shaft 65. A chain |0I passes over these two sprockets. It can readily be comprehended that as the shaft 56 is driven by means to be presently described in detail, that both of the vconveyors I2 and I3 are simultaneously operated and at the same rate of speed.`

'I'he shaft 56 of conveyor I2 is driven from the shaft 96 through intermittent mechanism which will now be described in detail. In the plane of the two shafts 56 and 65 is provided a boss |02 which is-formed on the wall 82 of case 8| and extends inwardly into the interior of case 8|. This boss has rigidly mounted in it a stub shaft |03. This shaft has rotatably mounted on it a pinion |04,

being a part of a Geneva movement for operating c the shaft 56. 'I'he pinion |04 meshes with a gear |05 integral with the sprocket 99 previously re ferred to and another part of said Geneva movement. The gear |04 has an integral bevel gear |06 which meshes with another bevel gear |01 fast on the shaft 96. Gear |04 is held rotatably mounted upon stub shaft |03 b y means of a head |08 formed on the end of said shaft. The shaft 96 travels in the direction of the arrow and causes movement of pinion |04 through the two beveled gears |06 and |01. Pinion |04 is constructed with gear teeth |09 which are adapted to mesh with gear teeth II on the gear |05. Pinion |04 is further formed with a cylindrical portion |I| `adapted to successively mesh with arcuate portions |I2 and H3 and ||4 on the gear |05 situated between the various gear teeth I I0 of said gear. By means of this construction it can readily be comprehended that every time the shaft 95 is rotated one revolution that pinion |04 makes a corresponding revolution. During the period that the cylindrical part I I of this pinion engages the arcuate portion H2 of gear |05, gear |05 remains ter of the sprockets 54 and 4GII of the two con-.

veyorsA I2 and I3 is such that one-third of a revolutionv of shafts 56 and 65 will progress the two conveyors I2 and I3 a distance equal to the distance between the various blades 260 and 68 on said conveyors. In this manner one revolution of shaft 96 procures movement of the two conveyors I2 and I3 equal to the distance between said blades so that the blades always come to rest at the same positions which are indicated in Fig. l when the Geneva movement causes locking of the gear |05 and cessation of movement of said conveyors.

For the purpose of operating the turnover device 4 a short shaft |I5 is employed which is journaled in a bearing IIS issuing inwardly from the wall 62 of case 9|. This shaft is' disposed between the two runs of the chain |0| and extends through the case 62 having secured to it upon its outer end a sprocket wheel ||1. A chain I8 passes over this sprocket wheel and over another sprocket wheel I|9 fast on shaft |69 o n which the turnover device is mounted. As shaft ||5 is rotated the turnover device is also rotated.

Shaft |I5 is driven 4from shaft 96 as follows: 0n the extreme end of shaft 65 of conveyor I3 is rotatably mounted a pinion |20 of another Geneva movement. This pinion meshes with a gear |2| of said Geneva movement fast on the shaft II5. A bevel pinion |22 is integral with pinion |20 and meshes with a bevel pinion |23 fast on shaft 96. Pinion |20 is quite likerthe pinion, |04 and the gear I 2| is quite similar to the gear |05 excepting that the latter gear is formed with two arcuate portions |24 and |25 instead of three as is the case with gear |05. Inasmuch as the shaft 69 has but two blades 13 and 14 on it the shaft ||5 is given but two turns for each revolution of the shaft 96. The teeth on the pinion |20 and the gear |2| are so arranged that the turnover device I4 operates when the two conveyors |2- and I3 are motionless and so that the said turnover device is Without motion when the two conveyors I2 and I3 are operating. I'he stationary position of the turnover device is shown in dotted lines in Fig. 7, while the position of said turnover device in which the same is beginning to turn over the doughnuts I have shown in full lines in this figure.

The transverse conveyor I6 previously referred to is best shown in Figs. 2 and 9. This conveyor consists of two chains |26 and |21. These chains have attached to each of the links thereof, slats |29 which forms a continuous belt covering the entire surface of the conveyor. At suitable intervals are provided blades |30which extend up' which are secured to the sides 45 and 46 of the portion of the receptacle in which the transf verse conveyor is mounted. Bearings |34 and |35 are closed at their ends so that the cooking liquid is prevented from leaking through the same and out of the receptacle II. Similar sprockets, shafts and bearings are provided at the other ends so arranged that the blades |30 of said transverse 5 conveyor Just clear the anges 6I of the conveyor To permit the operation of conveyor I2 during cessation of movement of conveyor I6 the blades 260 are provided with vertical slots |36 which are of such width to receive the said blades |30 as the conveyor I2 is operated.

The doughnut former I5 previously referred to may be of any suitable construction such as now are known in th'e art. A doughnut former of the type shown in Patent No. 1,747,503 to C. E. Carpenter has been illustrated. 'Ihe mechanism thereof forming no particular feature of the invention has hence not been shown in this application. The doughnut former I5 consists of a receptacle |31 open at the top and into which the dough is placed. 'I'his receptacle is formed with a hopper bottom |38 and terminates in a nozzle |39. The receptacle |31 is attached to a portion |40 of post 2| which extends upwardly above the f horizontal frame member I9. For this purpose 25 two bands I 42 and |43 are employed which encircle the said receptacle |31 and ,are formed with nuts |44 by means of which the said bands may be secured to the outwardly extending flange |45 of portion |40 of post 2| through bolts |46. The doughnut former I5 further includes a cut oit head |41 which is mounted on the end of a vertically reciprocable spindle 48. Said former further includes a piston, not shown, mounted on a sleeve |49 in which the spindle |46 is vertically slidable. Both these parts are arranged for vertical sliding movement as disclosed in said patent or in any other suitable manner. The upper end of the spindle I 49 is provided with a collar |50 by means of which the same may be reciprocated and sleeve |49 is constructed with a similar collar |5| serving a like purpose. The nozzle |39 is so situated that the same deposits doughnuts at the locality indicated in dotted lines at |52, in Fig. 2. The lower edge |53 of nozzle |39 45 is just above the level of the cooking liquid in the receptacle which prevents splashing of the liquid as the formed doughnuts are discharged into the same. The vnozzle |39 is situated medially between the position of two of the blades |30 50 which are procured when the conveyor I6 comes to rest. i

For the purpose of operating the doughnut vformer I5 and the transverse conveyor I6, the

transmission device I8 is employed. This mech- 55 anism will now vbe described in detail.

The transmission mechanism I6 comprises a case |54 having a rear wall I 55, a top |56, a bottom |51 and ends |59 and |59, said case being open at the forward portion thereof. For closing 60 this portion of the case, a cover |60 is employed which is adapted to be secured to a ange |6| f extending perimetrically about the various walls of the case. Cap screws |62 passing through the cover |60 are threaded into this flange. I'he 65 bottom |51 of the case |54 is bolted to the flange 21 of frame member I9 by means of bolts |63 which pass through said flange and which are threaded into bosses |64 formed upon the interior A of the bottom |51. A leg |65 issuing outwardly 70 from the wall |59 of said case also has bolts |66 extending therethrough which pass through the ange 21 of frame member I9 in the same manner as the bolts |63. The case |54 is braced through a diagonal brooe |61 which is bolted 76 2,042,262 through bolts lss and se to the bottom les and i to the post 2|. By means of this construction case |54 is rigidly supported with respect to the framework of the doughnut machine."

Within the case I 54 is rotatably mounted a. drive shaft |10. This drive shaft is journaled in bearings |1| and |12 formed in the end walls |59 and |58'of the case proper. Shaft |10 has attached to it a worm gear |13 which meshes with a worm |14 (Fig. 4) fast on a shaft |15. Shaft |15 extends transversely of the shaft |10 and is journaled in bearings |16 and |11 formed in the bottom |51 of case |54. This shaft projects outwardly of the case and has attached to it a pulley |18. A belt |19 passes over the pulley |418 and over` a pulley |80 of a motor |8I resting upon the fioor of the, buildingin which the machine is'disposed. The shaft |10 serves to operate the shaft 96 previously referred to. For this purpose two couplings |82 and |83 are employed which are attached to the shafts |10 and 96 respectively. 'I'hese couplings have further attached to them a oating shaft |89 by means of which a drive is afforded between shafts |10 and 96. Within the case |54 is rotatably mounted a counter shaft |85. This counter shaft is journaled in bearings |80 and |81 formed on the end walls |59 and |59 of case |54. Upon this shaft is rotatably mounted a gear |88 of a Geneva movement, the pinion |89 of which is mounted on the drive shaft |10. The pinion |89 is provided with teeth |90 and a cylindrical portion I9I similar to the parts of the Geneva movement previously described. The gear |88 is constructed with teeth |92 adapted to mesh with the teeth |90 and with an arcuate portion |93 adapted to be engaged by the cylindrical portion |9| of the pinion |89. Shaft |10 travels in unison with the shaft |85 and one revolution of the said shaft |10 procures one revolution of shaft |85. The teeth |90 extends over half of the circumference of the gear |89 so that shaft |85 is caused to rotate for a period somewhat greater than half the period of rotation of shaft |10 and to remain idle for the remaining portion of the rotation of said shaft.

integral with the gear |88 is a spur gear |94 which meshes with a pinion |95 best shown in Figs. 3 and 9. This pinion is fast on an auxiliary shaft 90 which shaft is journaled in two bearings |91 and |98 formed in the case |54.

The ratio of the gears |95 and |94 is one to four so that four doughnuts are delivered to the longitudinal 4conveyor by the cross conveyor whenever one cycle of movement of the various parts of the invention are completed.

For operating the transverse conveyor I6, shaft |85 is utilized. This shaft has mounted upon the end of it a sprocket |99. A similar sprocket 200 is secured to the shaft |33. A chain 20| passes over these two sprockets. Conveyor I6 and the sprockets |99 and 200 are so designed that one revolution of shaft |85 procures a movement of said conveyor equal to the distance between the blades |30 thereof. Whenever shaft |85 comes to rest, these blades are in a position to be received within the slots |36 of blades 260 of conveyor |2. p

The shaft |85 is driven from the shaft .|96 as follows: This is accomplished through a Geneva movement illustrated in detail in Fig. 5. Fast on the shaft |96 is a pinion 202 which is part of the said Geneva movement and which is provided with teeth 203 and a cylindrical portion 209. This pinion meshes with a gear 205 fast on shaft |85. Gear 205 is provided with 4teeth 206 and a single arcuate portion 201 adapted to engage the cylindrical portion 204 of the Geneva movement. During rotation of the shaft |96 the shaft |85 is caused to alternately rotate and remain stationary.

The doughnut former I5 is operated from two cams 208 and 209 attached to a sleeve 2|0 rotatably mounted on shaft I 85. The sleeve 2I0 has attached to it a gear 2|| forming part of another Geneva movement. A pinion 2| 2 also part of this Geneva movement is mounted on the shaft |96 and may be constructed integral with the pinion |95. This Geneva movement operates to rotate the sleeve 2|0 intermittently, one revolution of said sleeve for a corresponding revolution of the shaft |98. The Geneva movements operating the shaft |85 and the sleeve v 2|0 are so timed lthat the conveyor I5 and the doughnut former I5 are operated alternately.

Operating, in conjunction with the two cams 208 and 209 are two push rods 2|3 and 2M. These push rods are slidably mounted in guides 2 l5 and 2 l0 which are detachably secured to the case |59 in any suitable manner. 'I'he rods 2|9 and 2 I8 extend upwardly above said case and are further slidably mounted in guides 2|1 and 2|8 formed on a bracket 2|9. Bracket 2|9 is bolted to the upper end of the portion |40 of post 2| through bolts 220. On the rods 2|3 and 2|9 are rigidly secured collars 22|. Compression coil springs 222 encircle the said rods and are seated against the undersides of the guides 2| 1 and 2|9 and against the collars 22| and serve to urge the two rods downwardly and in contact with the two cams 208 and 209. On a standard 223 issuing upwardly from the bracket 2|9 are mounted for oscillation two swinging levers 228 and 225. Pins 226 and 221 pass through these levers and are secured to the standard 223 and serve as fulcrums on which the said levers oscillate. The lever 220 is connected through a fork 228 with the collar |50 while the lever 225 is connected through a fork 229 with the collar |5|. Links 230 and 29| pivoted to the ends of the rods 2|9 and 2M are also pivoted to the ends 232 and 233 of the levers 224 and 225 and serve to move said levers vertically and in opposite directions to the movement of said rods` as the same are reciprocatedthrough the two cams 208 and 209. By means -of the particular construction shown, the piston and head |41 of the doughnut former are so operated as to successively extrude formed parcels of dough which are periodically discharged into the cooking liquid in the receptacle 'I'he operation of my invention is as follows: Assuming the conveyors l2 and |3 to be'stationary, gear |04 is engaging the arcuate portion I2 of gear |05 and shafts 56 and 65 are stationary.`

During such disposition of parts, gear teeth 90 of gear |89 are engaged with gear teeth |92 and gear unit |88|94 is being rotated.

'Through the action of gears |94 and |95, shaft the formation and ejection of a doughnut from the nozzle |39 of doughnut former |5. The discharge of doughnuts occurs between two of the blades |30 of conveyor I6. The doughnut is discharged into the grease in close proximity to the surface thereof and gently sinks into the grease ,entire cooking operation thereof.

until it rests on the slats |29 of conveyor I8. As soon as the movementI of sleeve 2|0 terminates, shaft |85 is rotated. This causes the conveyor I6 to be progressed through the action of chain 20| and sprockets |99y and 200, causing thesaid conveyor to travel a distance equal to the distance between the various blades |30. During such movement, the doughnut is brought into the path of travel of conveyor I2. During the four rotations of shaft |96, four doughnuts are formed, deposited and conveyed, the first doughnut being delivered to the far side of conveyor'l2 andthe last doughnut to the near side of the conveyor I2. Gear unit IBS-|94 is then held stationary through the cylindrical part I9I of pinion |89 and the arcuate portion |93 of gear |88. When the conveyor I6 comes to rest, blades |30 are exactly opposite the slots |36 in the blades 60 of conveyor I2. This conveyor is then moved forwardly a distance equal to the distance between blades 60 which removes the doughnuts from the conveyor I and progresses the same along the receptacle II. During the formation and movement of the doughnuts by conveyor I6, the turnover device I4 is being operated which takes the doughnuts from the conveyor I2, turns them over and delivers them to the conveyor I3. In the subsequent operation of the conveyors, the conveyor I3 further progresses the doughnuts through the receptacle II, the

doughnuts being finally discharged from the end of the receptacle through the upwardly inclined run Il of conveyor I3.

Although I have shown the machine designed to convey four rows of doughnuts abreast, it can be readily comprehended that the machine may be constructed to handle three, five or any other number of columns of doughnuts within reasonable limits.

My invention is highly advantageous in that a machine is provided in vwhich doughnuts are positively formed and handled throughout the A single doughnut former is used which is stationary and discharges at a single location so that filling of dough in the same and adjustment in maniputhe spirit of my invention.
